GZip content encoding for wasm and svg

## Feature Request

I have a tool that combines all the SVG files that are used in the repo into a single SVG sprite and use css to select the correct sprite.
This file gzips well to around 25% of its original size. Is it possible to enable compression for Assets?

## Implement Suggestion
Similar to as you can do with
`asset!("/assets/icon.png", AssetOptions::image().with_avif());`
to
`asset!("/assets/sprites.svg", AssetOptions::image().with_gz());`
Or is it possible I can manually compress the file and set the response header: "content-encoding: gzip" for that resource?

I had a look at to reduce the size of the wasm
[https://dioxuslabs.com/learn/0.5/cookbook/optimizing/#build-configuration](https://dioxuslabs.com/learn/0.5/cookbook/optimizing/#build-configuration)
It greatly reduced the size of the server side binary but only reduced the wasm by 5% which I'm mainly interested in.
Are there tips and tricks to reduce the size of the wasm bumdle?
